The present invention relates to a production environment safety analysis method, device, and system. The method comprises: acquiring multiple hierarchies of an indication system influencing production environment safety and safe production indicators of each hierarchy, the multiple hierarchies at least comprising the lowest hierarchy, at least one intermediate hierarchy and the highest hierarchy; using an analytic hierarchy process to calculate the weight values of the safe production indicators of the lowest hierarchy and the intermediate hierarchy; acquiring historical data of the safe production indicators of the lowest hierarchy of multiple analysis objects in a predetermined period; normalizing the acquired historical data of each single safe production indicator, the basis of all the historical data of the same safe production indicator of the multiple analysis objects in the predetermined period; and calculating the safe production index of the highest hierarchy according to the normalized historical data of the safe production indicators of the lowest hierarchy, the weight values of the safe production indicators of the lowest hierarchy and the weight values of the safe production indicators of the intermediate hierarchy.
